On Saturday night in Las Vegas, boxing's pound-for-pound king, Floyd "Money" Mayweather 44-0 (26 KOs), will put his unblemished record on the line against 23-year-old rising superstar Saul "Canelo" Alvarez (42-0-1, 30 KOs).

This fight is expected to trump the 1.5 million pay-per-view audience from the May 2012 Mayweather-Miguel Cotto bout, but come in under the 2.5 million PPV record set by Mayweather-Oscar De La Hoya in 2007. The boxing odds were posted in early May when Mayweather tweeted his opponent would in fact be Alvarez, and varied in Las Vegas from minus-250 on Mayweather and plus-200 on Alvarez at the Las Vegas Hotel Sportsbook to minus-225 and plus-185 at Harrah's. The total rounds proposition odds were consistent at 11.5 rounds (over minus-300/under plus-250). Offshore betting shops like The Greek opened the fight as low as minus-220/plus-180.

Bettors haven't seen Mayweather this low as a betting favorite since he was minus-185 against De La Hoya in 2007. However, Alvarez will enter the ring as an underdog for the very first time in his career. Can he be the first to beat Mayweather?

Let's take a look at where the money is going in Vegas and my best bets for the fight and a couple of proposition wagers.
